+ The Suspend state is a power saving feature which is the lowest level of

+ When your computer is in the Suspended state, computation will not be
+ performed until normal activity is resumed.
+ It will not resume until signaled by an external event such as a keyboard
+ button press.
+ It generally takes a few seconds to suspend and then resume your computer.

+ </para>
+ </caution>
+ <para>
+ The Hibernation state saves the complete state of the computer to hard
+ disk and turns off the power, so that the computer appears to be off.
+ It will not resume until signaled by an external event such as a
+ keyboard button press.
+ This is the lowest power sleeping state available.
